A stackable plastic box blank (30) constructed using a reinforcing net (2) made of a first plastics material of rubber-modified polypropylene to form hinges, and a second plastics material injection moulded in the spaces between the elements of the net (2) to form panels and flaps. The first plastic has a melt index less than the second plastic allowing the both materials to fuse to form a blank (30). Load bearing panels (42,46,62,66) are provided with convex projections, which snap-fit into rectangular openings in the end panels (44,64). Base panel (54) and lid flaps (50,58) are provided with concavities to provide anti-slip with adjacent boxes when in either erected or collapsed state.
